The Microscope

The Simple Microscope

A converging lens acts as a simple microscope (magnifier) or magnifying glass as shown below. If an object is placed in front of the lens between the optical centre and the principal focus, the image formed will be enlarged, erect and virtual. The magnifying glass is used for reading tiny writings and for viewing specimens in the laboratory

Magnifying Glass

Summarily;

A simple microscope sometimes called a magnifying glass. It consists of a single converging lens with a long focal length. The object is position between the principal focal and the optical pole. The image produced is:

  • magnified
  • erect
  • virtual

 

The Compound Microscope

The compound microscope consists of two converging lenses, the objective lens and the eye piece.
